A TEETER-TOTTER APPROACH TO ARRAY SCANNING
Abstract
A new compact, electromechanical scanning array in which a small mechanical ngular motion of a scanning lever arm can cause a wide degree of eam steering is demonstrated. The teetertotter scanning array uses a ganged arrangement of helical delay lines as phase shifters and directional couplers as power dividers. Any desired antenna illumination can be obtained by simply varying the coupling of each directional coupler. Radiation patterns at scanning angles up to 60 degrees off broadside were recorded for a uniform distribution, a -20 db and a -30 db Tschebyschef antenna istribution. (Author)
